Research Gaps and Opportunities for Secure Access Service Edge

This paper provides a contemporary discussion of security as a service from a network perspective and discusses state-of-the-art research conducted within a framework known as Secure Access Service Edge (SASE) (pronounced 'sassy'). SASE is a network security framework proposed by Gartner (2019) (MacDonald, Orans and Skorupa, 2019). This paper gives brief description of cloud concepts and technologies, focuses on network security in the cloud and aims to provide researchers with subjects of future research in SASE. To achieve the aim, the authors evaluate existing papers on SASE and its core components to identify gaps in the literature currently available on SASE.
